Study Notes

Internet

Defined as a global system of interconnected computer networks, often referred to as an information superhighway.

Main Memory

RAM (Random Access Memory): Temporary storage for program instructions and data, composed of integrated circuits.
ROM (Read Only Memory): Non-volatile memory that permanently stores programs and data, also made of chips.

Secondary Memory

Also known as external memory; includes various storage media (fixed or removable) for data and programs.

Input and Output Devices

Input devices: Send information to computers for processing.
Output devices: Reproduce or display processing results.

Classification of Computers

Microcomputer: Small computers built around a microprocessor; commonly known as Personal Computers (PCs), including desktops and laptops.
Minicomputer: Inexpensive computers for single departments, often dedicated to specific tasks with limited power but compatible with laboratory devices.
Mainframe: Large storage and computational power computers, designed for reliability with redundancy for partial failures.
Supercomputer: Highly powerful and expensive computers used for advanced computations, such as nuclear simulations and weather modeling.

Digital Age, Information Age, and Computer Age

Terms highlight the pervasive use of technology in human activities and continue to evolve with new tech developments.

Media in the Digital Age

Media refers to communication methods using various tools to connect people, such as television, radio, cellular phones, and social media.
The Message: Content ownership includes both user-generated and professionally produced forms (e.g., blogs, vlogs).
The Medium: Tools that convey messages; example includes social media platforms.
The Messenger: Individuals or organizations delivering messages, often referred to as 'media' (e.g., broadcasters).

Evolution of Media

Transformation based on how information is presented and connections are established.

Overview of Current Trends

IoT and Smart Home Tech: Allows control of household appliances via mobile devices, enhancing convenience.
Augmented Reality and Virtual Reality: Advances highlighted by interactive games like Pokémon Go and the Oculus Rift headset.
Machine Learning: A subset of AI focusing on using data and algorithms to emulate human learning processes.
Automation: Technology performing tasks with minimal human input across various sectors, enhancing operational efficiency.
Humanized Big Data: Analyzing large data volumes for insights that aid decision-making, exemplified by apps like Waze.
Physical-Digital Integrations: Converting physical processes into digital forms for efficiency; example includes paperless operations.
Everything On-Demand: Internet connectivity enables immediate access to information and services via smartphone apps, including music and ride services.

Impact of ICT and Ethical Issues

Positive Effects: Enhanced access to education, information, and improved security.
Negative Effects: Decreased personal interaction, job loss, and ongoing security concerns.
Ethical Issues: Concerns include plagiarism, exploitation, libel, and software piracy.
